Workflow overview: As a GDExtension, godot-cpp is more complicated to use than GDScript and C#. If you decide to work with it, here's what to expect your workflow to look like: Create a new go...

The 'Creating a simple plugin' step states: "In our demo project, we'll create a scene containing a Node called "Main" and we'll save it as main.tscn. We'll come back to that later."

Should this Node be a 2d Scene node or just a regular Node?

[kburchfiel]

Looks like a regular Node (e.g. not a 2D Scene Node) works just fine.

Ik this is 5 Days old, but I just usually use a Node2D knowing you are setting up a 2D scene, I suppose it can be seen as redundant though. Pretty neat being able to use c++ isn't it!

Here's a CMakeLists.txt I ended up with:

cmake_minimum_required(VERSION 4.0)
project(godot_cpp_example)

set(CMAKE_CXX_STANDARD 26)

add_compile_definitions(TYPED_METHOD_BIND)

add_executable(${PROJECT_NAME}
        src/gdexample.cpp
        src/register_types.cpp)

target_include_directories(${PROJECT_NAME} PRIVATE "godot-cpp/gen/include")
target_include_directories(${PROJECT_NAME} PRIVATE "godot-cpp/include")
target_include_directories(${PROJECT_NAME} PRIVATE "godot-cpp/gdextension")

Obviously, you won't use it to build the extension, but it helps with the code completion.

Also I had to change the script at the end to

extends Node

func _on_gd_example_position_changed(node: Object, new_pos: Vector2) -> void:
	print("The position of " + node.get_class() + " is now " + str(new_pos))

otherwise it refused to work. I have no idea why, because this is my first time using Godot, so maybe I'm just doing something wrong.

[KevysNotHeavy]

Hmm, is it tied to the gd vscode extension or smth.. I use vscode and after finding out how to gen the classes and variants I had no issue

Followed every step of the tutiral but when i go back to Godot, i can see the bin/ folder, but i can't see the .x86_64.dll from the Godot's folder, but if I open the folder from (for example) Vs Code, i can see it. Currently using Godot 4.5 on a Winodws 11 PC
